I remember Yuma Ariz as a kid helping my dad work on construction equipment on a site out in the middle of the desert. It was so hot that you couldn`t lay the tools down in the sun, if you did when you tried to pick them up they would burn your hands. The only shade was inside the trucks or underneath them. Inside was NOT an option, NO BREZE, you would be cooked in a matter of minutes. We had two igloo coolers, one full of icewater for us and the other full of water for the tools. Heat stroke, YEA I`v had it more than once! NOT FUN. And to this day I can`t take much heat or sun. In mid summer out there in that desert it isn`t uncommon for the temps to approach 118 degrees and into the 120`s NO, No humidity. But still plenty hot!
